Notes on 400 agents VM configuration

Resource Reservation

The Resource Reservation has been enabled for all the three Unified CCX Profiles wherein any one of the Unified CCX Profile can be deployed through the single OVA. The Unified CCX 8.5(1) and 9.0(1) has been successfully qualified with vCPU reservations at 900 MHz per vCPU.

Resource reservation helps us to achieve the most optimum levels of utilization of underlying physical resources of ESXi 4.1 and ESXi 5.0 qualified Cisco/HP/IBM servers either when Unified CCX VM has been deployed with multiple instances of other Unified CCX VM or co-resident with any other Unified Communications application VMs on the same server.

The resource reservation helps the user to confine the VMs to respective resources and also helps to achieve the highest possible level of utilization of underlying physical resources as long as the sum of all the VM resources are not oversubscribed.
